Joanna

She met a prince, Glenn, while he was on vacation near her home. The two planned to elope, but instead Joanna used him as part of her midterm exams - turning a true love into a frog. Her final exam was to turn him back into a human, but she found this difficult to complete as she lacked confidence and her home was being haunted, making it difficult to study.

Once she regained to confidence to try at her final exam, she was able to turn Glenn back into a human.
